en.Wedoany.com Reported - A consortium led by Macquarie Asset Management has injected additional equity into Southern Water, bringing the total equity investment in the company since its acquisition in 2021 to £2.8 billion. The consortium includes Asterion Industrial Partners (AIP), an independent European infrastructure investment management firm headquartered in Madrid, with approximately $10 billion in assets under management. AIP will provide the majority of the new capital and become a minority shareholder in Southern Water.

This latest investment fully delivers on the £1.2 billion equity support package announced in July 2025. Since Macquarie acquired the business in 2021, Southern Water has not paid any dividends to shareholders. The proceeds from the equity financing will support Southern Water's record £8.5 billion AMP8 investment plan.

In the first year of the 2025-2030 AMP8 period (ending March 31, 2026), Southern Water stated that its operational transformation continues to make progress, with improvements across multiple indicators including water supply interruptions, leakage, and external sewer flooding, while network capital investment reached record levels.

Lawrence Gosden, Chief Executive Officer of Southern Water, said that over the past four years, the company has worked hard to transform, significantly increasing investment in services and infrastructure while improving operational performance. The additional equity support enables the company to implement an £8.5 billion investment plan over the next five years to improve customer service, enhance infrastructure resilience, and continue reducing environmental impact. Gosden thanked Macquarie for its long-term investment and industrial expertise, and welcomed Asterion Industrial Partners as a new shareholder, stating that its investment is a recognition of the company's progress and confidence in its future plans.
